摘要:
以我国几个典型区域的气候条件情况和在此气候条件下光伏组件出现PID效应现象为基础,研究了在不同实验室温度、相对湿度、电压、时间等测试条件下,不同抗PID等级光伏组件的微观结构和发电性能的变化.通过对典型气候区域环境温度和相对湿度的对比分析,结合光伏电站运行电压和时间两个导致光伏组件PID效应的关键因素,得到了光伏组件在典型气候区PID效应的实验室模拟检测方法,即模拟湿热气候环境温度和相对湿度、组件运行电压和运行时间分别为85℃和85%,-1000 V和96 h;亚湿热气候为60℃和85%,-1000 V和96 h;暖温气候为60℃和60%,-1000 V和96 h,合格判据均为最大功率衰减不超过0.8%.
Abstract:
In this study, based on the climatic conditions and PID phenomena of several typical regions in China, different laboratory PID test conditions, such as temperature, relative humidity, voltage and time, were carried out for PV modules with different anti-PID grades. The changes of microstructure and electrical properties were studied. Through the comparative analysis of the ambient temperature and relative humidity of the typical climate regions, combined with the operation voltage and time of the PV power plants, the key factors that cause the PID effect of the PV module, the PID test methods of PV modules in typical climate regions was achieved. Namely, the conditions for the hot and humid climate zone are 85 ℃, 85%RH, -1 000 V, 96 h; the conditions for sub-humid climate zone are 60 ℃, 85%RH, -1 000 V, 96 h, and the conditions for Warm weather zone are 60 ℃, 60%RH, -1 000 V, 96 h. Qualified criteria are the maximum power attenuation of not more than 0.8%.
